Can't figure out test error in laravel?

Question

PHPUnit

I hand over the project, at the level of tests such an error takes off.

app_1  |  ------ ----------------------------------------------------------------------- 
app_1  |   Line   code/tests/Feature/UrlControllerTest.php                               
app_1  |  ------ ----------------------------------------------------------------------- 
app_1  |   68     Parameter #1 $body of static method                                    
app_1  |          Illuminate\Http\Client\Factory::response() expects array|string|null,  
app_1  |          string|false given.                                                    
app_1  |  ------ -----------------------------------------------------------------------

here is the UrlControllerTest.php file with line 68 Http::fake([$url => Http::response($html)]);

public function testChecks(): void
    {
        $data = ['id' => 1, 'name' => 'https://test.ru'];
        $url = $data['name'];
        $expected = [
            'url_id'   => 1,
            'status_code' => 200,
            'keywords'    => 'keywords test fixture',
            'h1'          => 'Header test fixtures',
            'description' => 'description test fixture',
        ];
        $html = file_get_contents(__DIR__ . '/../fixtures/test.html');
        Http::fake([$url => Http::response($html)]);
        $response = $this->post(route('urls.checks', $data['id']));
        $response->assertSessionHasNoErrors();
        $response->assertRedirect();
        $this->assertDatabaseHas('url_checks', $expected);
    }

If I understand correctly what the test swears at, then it turns out that Http::response comes false ?
If so, where from? The test is called 1 time with a fixture where the line (layout) lies .... maybe I don’t understand what exactly the error says? Or what is going on here?
